DOUBLE-ROLLER DOOR-HANGER.

Application led May 2, 1916.

T0 all lwhom t may concern.'

Be it known that I, JAMES T. BRADY, a citizen of the United States, residing at Shawnee, in the county of Pottawatomie i and State of Oklahoma, have invented a new and useful Double-Roller Door-Hanger,

of which the following is a specification.

The present invention relates to an improved door hanger, particularly for use 2 with freight car doors, and has for an object to provide an improved hanger adaptable to tracks of the Z-bar type of the usual dimensions.

Another object of the invention is to prof: vide the lower end of the body plate of the also from the upper edge of the door beneath the Z-bar, and behind the lower roller. rThus, the drain opening in the outer side of the hanger drains olf all moisture. collecting behind or in front of the lower roller, and prevents pocketing of the moisture in the bottom of the hanger, and the consequent rotting and weakening of the door.

A further object of the invention is to provide a structure of this character wherein the rollers turn upon pivot pins, which are fixed so that the rollers and the pins take up the wear, and the sides of the hanger are not subjected to the wear usually placed upon them. Thus, rollers and pins may be easily renewed and after considerable wear, it is not necessary to discard the entire hanger.

Other objects and advantages of the in- 'f vention are: to provide a structure which has an inner fiat face carrying .a transverse rib, engaging a peculiarly formed lower roller, to offset the roller inwardly and provide between the same, and the flat face or plate, a space to receive the depending flange of the Z-bar; which is of peculiar integral form, relatively flat, and which may be mortised, to a slight extent only, into the outer face of a door at the top thereof, without impairing the strength of the door, and

at the same time providing a hanger which lies relatively close and fiat against the outer side of the door; which prevents access of rain, or the like, working in under the Z-bar and over the top of the door; and wherein the lower bracket or strip portion of the hanger is relatively broad and hasbolt receiving openings in its opposite lateral eX- tremities, and in its lower extremity to thus secure a firm purchase of the bracket or strap against the door, and prevent the tearing out of bolts and rivets as is frequently the case in the brackets or straps of the usual construction.

Various other objects and advantages of this invention will be brought out in the following description of the present preferred embodiment of the invention, the same being illustrated in the accompanying drawing, wherein- A Figure l is a front elevation of the improved hanger. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertial central section, taken through the hanger, as applied to a door and engaging a. Z-bar of the usual form. Fig. 4 is a horizontal section through the lower roller and adjacent parts of the hanger, taken on the line L i of Fig. 1, and looking downwardly in the direction of the arrow. Fig. 5 is a vertical central view, taken through the hanger between the lower roller .and the body plate on the line 5*5 of Fig. 3. Fig. 6 is a detail perspective view of the lower roller.

Referring to this dra-wing, wherein like parts are designated by similar numerals of reference throughout the several views, 10 designates the side of a car, or other suitable support to which is attached a Z-bar of the usual form and relative proportions, and which has a base or attaching flange 11 secured against the side 10 of the support, a horizontal outstanding intermediate or body portion 12, and a depending flange 13 at the outer edge of the body portion 12. In Fig. 3a door 14 is shown in proper position beneath the Z-bar.

The bracket constructed according to the present invention comprises an integral casting providing a relatively fiat vertical body plate 15, reinforced with a marginal flange or rib 16, which preferably extends outwardly from the plate 15. The body plate has near its upper and lower ends transverse openings 17, one near the upper end of the plate, and the ot ier opening 17 being located ne:` f `thelower end thereof. Concentric with each ot the openings 17 and in the outer face. oit the body plate 15, is a socket 18, which is ot' angular or other non-circular torni, and

vvhich is provided preferably in a boss 19 raised upon the outer tace of the plate 15 about the opening 17. The plate 15 vhas a flat bearing inner wall or tace, which is uninterrupted fromV top to bottoni except by a horizontal rib 2O which lies in the horizontal plane of the lower opening 17, and is interrupted by said opening, as shown to advantage in Figs. 3, 4; and 5. This rib 20 projects inwardly troni the body plate 15 for a purpose which will hereinafter appear.

The lower end of the body plate 15 is oil'- set inwardly as at 21, the inner tace oi? the offset portion lying substantially in the vertical plane of the outer face ot the rib 20. The upper and lower ends ot the body plate 15 are provided respectively with ears 29. and

` Q3, which extend horizontally inward 'from the respective ends of the plate 15, and are then turned abruptly downward and upward toward each other, as shown to advantage in Figs. 2 and 3. The ears 22 and 23 are equidistantly spaced troni the adjacent upper and lower ends ot the body plate, so that the lower ear E23 is oiiset slightly inwardly troni the upper ear 22. The tree ends ot the ears 22 and i3 are provided with transverse openings 24C, which register transversely with the openings 17 in the opposite ends of the body plate 15. The upper openings 1 7 and the registering upper opening 2% receive therein the opposite ends of a transversely extending rivet or pivot pin Q5. This pivot pin or rivet has an enlarged non-circular head Q6 adapted to seat in the socket 18, and be held therein from turning, so as to prevent the turning. ot the rivet 25. The rivet is introduced in vardly through the socket 18, opening 17 and through the opening 24: of lthe ear 22. The rear end of the rivet 25 is upset, as at 27, against the rear face of the earQZ to retain the rivet 25 in place.

The lower opening 17 and the lower opening Q4 are spaced farther apart than the npper corresponding openings by reason of the otfsetQl. A transverse rivet or pivot pin 28 passes inwardly through the lower socket 18, the opening 17, and through the opening 24 .of the lower ear Q3. The inner end ot the rivet 2S is upset as at 29 yto retain the rivet in place, and the outer end of the rivet 2S Ahas a non-circular head 8O seated in the socket 18 to hold the rivet QSroni turning. Freni Fig. 5, it will be noted that' the lower rivetfB intersects the'transverse rib 20 and g lies in the saine horizontal plane therewith.

, The improved hanger is' provided with two rollers, an upper roller 81, and a lower roller SQL ForA the-purpose of reducing the weight of the hanger, the upper roller 31 is recessed in its opposite sides as at 35, so as to leave a supporting web 34, intermediate the opposite ends ,of the hub of the upper roller. The hub 35 is preferably ot a length equal substantially to the distance between 'the inner tace of the body plate 15, and the opposite iace of the ear Q2. Thus, as shown in Fig. S, t ie upper roller 31 is held from vibration between the ear and the body plate, and is inounted upon the upper transverse rivet 25. The lower roller 32, as shown in Figs. 3, 41 and 6, is ot' substantially cup shape, the peripheral portion oi the roller comprises a laterally extending flange at the peripheral edge ot a supporting rib 36, which projects outwardly about the forward end of the hub 37. This hub l 37 abuts at its inner end against the inner tace ot the ear Q3 and is inounted on the lower rivet 28. The hub 37, however, does not extend across the entire distance between the body plate and the ear 23, but tcrniinates in abutting relation with the transverse rib 20. 'las shown, it may be desirable to provide a boss or bearing portion 38 on the iorward side oit-the roller 8i." concentric with the hub, and vconstituting substantially I a continuation of the saine. This bearing portion 38 projects outwardly from the we 35 a sutlicient distance to engage the rib 20 and take up wear on the lower roller and also reduce the frictional Contact between the rib and the roller. The rib 20 is provided for the purpose of spacing the lower roller 32 inwardly toward the ear 23 to itorni an opening or passage between the roller 32 and the body plate 15, sutlicient to receive the depending flange 13 of the Z-bar therein.

The body plate 15 is provided at its'lowei` end with a supporting bracket 39, which, as shown to advantage in Figs. 1 and 2, is preferably triangular in shape and which has its bolt receiving openings e0 widely spaced apart, and extending to a considerable distance at veach side of the body plate. Bolts Ll1 are passed through the openings i0 or the bracket 39, and are secured in the door 14. As the bracket is relatively large and eX- tends laterally troni the body plate 15, the bolts 11 are spaced apart a considerable distance, and thus the bracket is rigidly secured to the door and held roni twisting and tearing out the bolts Z11. For the purposeof reducing the weight of the hanger, the bracket 39 is in the form of a relatively narrow frame with a reinforcing inarginal bead 42 about the outer-edge of the trarne, so as to provide for a substantial bracket, and one which has an open niiddle portion, and which is of reduced weight. The otliset p0rtion 21 ot the body plate has a recess 43 in its lower end, the recess opening upwardly andl inwardly into the bottoni or housing formed between the body plate 15 and the lower ear 23.' Thus, moisture, water, and

the like, accumulating in the bottom of the hanger may readily pass out through the recess and be discharged outwardly of the door 14. The marginal bead 42 of the bracket 39 extends inwardly from the outer upper corners of the bracket and merges into a rearwardly extending flange 44, extending rearwardly from each edge of the body plate 15, and at the lower end of the latter. These iianges 44 are continued downwardly' along the edges of the offset portion 21 and terminate in the lateral edges of the lower ear 23. These flanges 44 close in the space between the lower roller 32, and the lower' end of the body plate 15, at the lower half of the roller. rlhe lower end of the offset portion 21 has a depending lip 45, which extends entirely across the bottom of the offset portion, and below the ear 23, this lip 45 constituting a shoulder or abutment for engagement with the outer face of the door 14 when the ear 23 is mortised into the outer face and upper edge of the door. rlhe lip 45, therefore, determines the position of the hanger on the door, and lies substantially in the same vertical plane with the bracket 39, so that the lip and the bracket lie flat against the outer face of the door. IThe opposite ends of the lip 45 merge into the lower edges of the upper portion of the bracket 39, as shown in Fig. 1, so as to reinforce the bracket and form a continuation thereof. The marginal head 16 of the body plate 15 is continued downwardlyy at each lateral edge of the body plate, the ends of the bead flaring downwardly and outwardly across the upper corners of the offset portion 21, and extending along the lower edge of the bracket frame. Concentric about each bolt opening 40 is a. circular rib 46, the same outstanding from the outer face of the bracket 39 at each corner thereof, and connecting the ends of the ribs 16 and 42, which reinforce the various arms of the bracket.

The hanger of this invention has an integral body portion including the bracket and the ears. The body portion is of such construction that it receives therein the rollers and their supports, the supports comprising the rivets or pins which do not turn in the body, so that there is practically' no wear or friction against the body or any part thereof. lThe rivets or pins are fixed in the body and take up the wear, so that when the pins and the rollers are worn to any appreciable extent, they may be quickly and easily renewed. The provision of the horizontal or transverse rib 2O across the rear face of the body plate 15 determines the position of the lower roller 32 and insures suilicient space between the roller and the body plate to accommodate the depending flange 13 of the track. The body of the hanger, and the mounting of the rollers, is such that the hanger may be quickly applied to tracks of Z-bar construction now commonly employed, and which are of the usual dimensions. Any tilting or lifting of the door brings the lower roller 32 against the under side of the horizontal flange 12 of the track, while the hanger is normally suspended upon the upper roller 31, which engages and rolls over the upper face of the horizontal flange 12 of the track. The depending flange 13 engages against the outer face of the web 36 of the lower roller, should there be any tendency to force the door 14 outwardly away from the track and the support 10.

1t is found in practice to produce a more efficient hanger by making the upper fixed pivot 25 of slightly greater diameter than the lower pivot 2S. '1`he upper pivot 25 is of substantially one-half inch in diameter, so as to afford a strong support and a relatively durable bearing for the roller 31, which carries the door 14. The lower pivot 28 receives but comparatively little wear and does not have to support the weight of the door 14. The lower pivot is, therefore, reduced in diameter, so as to add no unnecessary weight to the hanger, and at the same time have the required strength to support the lower roller 32. From Fig. 3 it will be noted that the lower ear 23 is the only part of the hanger which is mortised or embedded in the outer face of the door, so that but a relatively small mortise or depression is necessary to make in the top of the door. The average door is from lto 2 inches in thickness and the mostise is less than an inch in depth, so that the strength of the door is not impaired. rlfhe lateral flanges 44, which rise at the lateral edges of the lower ear 23 effectively close in the sides of the housing within the ear to prevent moisture and other accumulations from entering behind the ear and about the lower roller 32. The depending flange 13 of the track wards off moisture and other' accumulations from entering the top of this housing or inclosure.

lt will also be noted from F ig. 3, that the rib 20 on the plate lies slightly below the lower edge of the flange 13 of the track. Thus, if there is a tendency to tilt the bracket in either direction, one end or the other of the rib 2O is brought into contact with the lower edge of the flange 13. Such contact limits the tilting of the hanger, so that the door 14 is not permitted to swing down to any extent, should one of the hangers become detached from the end of the rail. The supporting bracket 39 is shown in the form of an open triangular frame with one of its arms arranged substantially horizontal and near the top of the door, so that the pivot receiving openings 40 at the top of the bracket are spaced wide apart to secure a firm purchase of thebracket upon the door. By providing a hanger wherein the rollers are spaced apart but a slight distance, such as of the bottom roller is caught in the bottomV of the ear 23 and directed outwardly through a drain opening 43. Thus, the walls of the mortise in the door are protected from rotting and weakening by moisture and the like, which collects around the opposite sides of the lower roller. rhe hanger of this invention is, therefore, provided with a means for completely draining the hanger whether the moisture'enters behind the lower roller and beneath the Z-bar track, or whether it drips oil of the depending flange 13 ofthe track and alls down between the front face of the roller and the plate.

W hat is claimed is:-

l. A one piece door hanger comprising a vertical plate with upper and lower openings in its opposite ends, a horizontal rib extending across the inner face and near the lower end of the plate, and upper and lower integral ears overturned inwardly and in spaced relation from the opposite ends of the plate, the ears each having an opening in its free end registering with they adjacent opening in the plate, a pin secured in each pair of openings, an upper roller` mounted on the upper pin for rolling contact upon the upper face of a Z-bar track, a
